提出一种基于模型的焊缝特征位置提取与识别方法.通过定义简单的参数化焊接接头模型,使用部分豪斯多夫距离(PHD)作为相似性度量准则,利用迭代匹配的方法使得焊接接头模型快速地逼近实际焊接接头的位姿.为了保证方法的可靠性与实时性,利用统计分析的方法设置相关的匹配参数,并通过将位姿参数空间定义在结构光平面而实现了参数空间的降维.实验结果表明,该方法在满足实时性的条件下保证了最后结果的精确性,满足实际应用的要求.
This paper proposes a model-based method to extract and identify the location of weld features.Through the definition of a simple parametric welded joint model and the use of part of the Hausdorff distance (PHD) as a measure of similarity, an iterative matching method is used to make the welded joint model Quickly approaching the pose of the actual welding joint.In order to ensure the reliability and real-time of the method, the relevant matching parameters are set by means of statistical analysis and the parameter space is reduced by defining the pose parameter space in the structured light plane The experimental results show that this method can ensure the accuracy of the final result under the real-time conditions and meet the requirements of practical application.
